In a recent change to Canadian immigration law C-3 means that millions of more Americans may now qualify for duel-citizenship with Canada.

This change is now of particular interest to some Americans in the wake of President Trump's immigration crackdown.

'Previously, Canadian citizenship by descent could only be passed down to one generation, from a parent to a child. But the new law opened up citizenship to anyone born before that date who could prove they have a direct Canadian ancestor — a grandparent, great-grandparent or even more distant ancestor;' according to MS Now.

'Those born on or after Dec. 15 need to show that their Canadian parent lived in Canada for 1,095 days.'

Under the new law, descendants of Canadians are already considered citizens but must provide proof to obtain a certificate of citizenship. Hayer estimated that there are millions of Americans who are Canadian descendants.

MS Now interviewed three peopleabout the new change.

Michelle Cunha, of Bedford, Massachusetts, said she decided to move to Canada after reflecting on decades of political activism and deciding she had 'nothing left to give.'

'I put in my best effort for 30 years. I have done everything that I possibly can to make the United States what it promises the world to be, a place of freedom, a place of equality,' Cunha said. 'But clearly we're not there and we're not going to get there anytime soon.'

Troy Hicks, who had a great-grandfather born in Canada, said he was spurred by an international trip.

'I recently went to Australia and you know, first words out of the first person I talked to in Australia was basically an expletive about Trump and the U.S.,' said Hicks of Pahrump, Nevada. 'It was just like, whoa, I walked off a 20-hour flight and literally the first words of somebody's mouth to me were that. ... So the idea of doing that with a Canadian passport just seemed easier, better, more palatable.'
